| Research Abstract |
We modified river dikes and adjusted the stream grade to remove the barriers for fish movement and also installed fish corridors to allow the fishes to move freely between rivers, irrigation ditches, and rice paddy fields at the Tenno River in the island. In the river, we have found little difference in the abundance and biodiversity probably due to the short length of time investigated after the modification ; we expect to find some responses from the fish if we continue the monitoring. On the other hand, the fish biomass significantly increased in the paddies where the fish passes had been set.
